MACHINE FOR SOLDERING VENT-HOLES.

SPECIFICATION forming part of Letters Patent No. 408,253, dated August6, 1889.

Application tiled October 1, 1888. Serial No. 286,918. (No model.)

llo all whom it may concern:

Be it ltnown thatI, EDWIN NORTON, a citizen of the United States,residing at Maywood, in the county of Cook and State of Illinois, haveinventeda new and useful Improvement in Machines for SolderingVent-Holesin Cans, of which the following is a specification.

The object of my invention is to provide a machine of a simple and cheapconstruction for soldering vent-holes, in cans.

My invent-ion consists in the novel devices and novel combinations ofparts and devices herein shown and described, and more particularlypointed out in the claims.

In the accompanying drawings, which form a part of this specification,and in which similar letters of reference indicate like parts, Figure lis a side elevation of amachine embodying my invention. Fig. 2 is afront View, and Fig. 3 a detail plan view, of the can-holder turret.

In said drawings, A represents the frame of the machine.

lthe shaft of the turret.

B is an interinittently-revolving turret or disk provided with a seriesof can holders or recesses b to receive the cans the vent-holes of whichare to be soldered. This turret is intermittently revolved from the drivin g-sh aft C by means of a cam C thereon, which operates a pawl-leverc, the pawl c of which engages the ratchet-wheel c2 on the countershaftc3, the counter-shaft c* having a bevelgear c4, which meshes with abevel-gear b on The pawl-lever c is operated from the cam C' by means ofa sliding connecting-bar C2. The turret B is locked in position, so thatthe can thereon will properly register with the soldering-tool D bymeans of a locking-bolt b2, which engages suitable locking devices orrecesses b3 on the turret B. The locking-bolt h2 is forced intoengagement with the turret by a spring ht, and it is withdrawn at properintervals by a cam if on the sliding bar C2.

The soldering-tool D has a tip d on its lower face suitable forsoldering the vent-hole of a can. The tool is secured to or madeintegral with a vertically-sliding revoluble shaft CZ. The shaft. d isgiven its revolving motion by means of a bevel gear d2 thereon, whichmeshes with a bevel-gear cl3 on the drivingshaft C. The shaft d isconnected by aspline d4, or other equivalentmeans, with its gear d2, sothat it may slide through said gear. The soldering-tool is given itsreciprocating motion by means of a cam di on `the shaft C, which engagesan arm d6, connected to the shaft d. The arm c is or should be providedwith a friction-roller di to bear against the cam. The soldering-tool Dis heated by a gasjet F, or other suitable heater.

By substituting an annular-faced. solderingtool adapted to fit thecap-groove in the can the same machine may be used for soldering on thecaps.

The turret B, as shown in the drawings, is provided with four canholders or recesses b. It may, however, be furnished with a greater orless number, if desired.

The soldering-tool D is furnished with an annular cavity in its upperend for the reception of the flame from the burner F. This annularcavity isindicated by the dot-ted lines in Fig. 2. By the revolution ofthe solderingtool D the flame from the burner is projected equally intoevery part of the annular cavity in the tool D, so that it is heateduniformly.

I claiml. The combination, with anintermittentlyrevolving turretfurnished with can-holders, of mechanism for intermittently revolvingsaid turret, a revolving vertically-reciprocating soldering-toolprovided with an annular cavity in its upper end to receive and confinethe flame, the Walls of said cavity being imperforate, so that the flamewill not be projected through the soldering-tool, mechanism forreciprocating and revolving said tool, and a burner F, for projectingthe flame into said annular cavity and heating said tool as itrevolves,substantially as specified.

2. The combination, with a can-holder, of a soldering-tool havin g arevoluble sliding shaft (Z, gears cl2 d3, shaft. C, and cam (l5, saidshaft d having an arm or projection engaging said cam for revolving andreciprocatinsaid soldering-tool, substantially as specified.

3. The combination, with shaft C, having cam C, of connecting-rod C2,paWl-lcver c, pawl c', ratchet c2, shaft c3, bevel-gear c4, and

IOO

can-holder turret B, having gear h on its shaft meshing With said gearc4,substantially as specified.

4. The combination, with shaft C, having cam C', of connecting-rod C2,paWl-lever c, paWl c', ratchet c2, shaft c3, bevel-gear c4, andcan-holder turret B, having gear h on its shaft meshing With said gearc4, said turret having recesses b3, a locking-bolt hspringb, and a camb5 on said connecting-rod C2, substantially as specified.

5. The combination, with shaft C, having cam C', of connecting-rod C2,paWl-lever c, paWl c, ratchet c2, shaft c3, bevel-gear c4, andean-holder turret B, having gear b on its shaft meshing with said gearc, solderingtool D, its sliding shaft d', gear d2, gear (13011 saidshaft C, cam d5, and arin d6, secured to said shaft CZ, substantially asspecified.

6. The combination, with shaft C, having cani C', of connecting-rod C2,paWl-lever c, paWl c ,ratchet c2, shaft c3, bevel-gears c4, andcan-holder turret B, having gear h on its shaft meshing' with said gearc4, said turret having` recesses h3, a locking-bolt b2, spring h4, a camb5 on said connecting-rod C2, solderingtool D, its sliding shaft d',bevel-gear d2, bevelgear d3 on said shaft C, cam d5, and arm d6, securedto said shaft CZ, substantially as specified.
